  • A novel test on the influence of spatial structure on the variance in local conditions

    Statistical parameters often vary across geographic landscapes. For instance, when the the variance of georeferenced random variables is not stable, this might hint on variegated processes or contextual conditions in different sub-regions. Analysing such heterogeneous areas is challenging because an explicit consideration of this so-called spatial heterogeneity is required. Various approaches exist that take account…

  • DFG Summer School “VGI”

    Last week, our colleagues Franz-Benjamin Mocnik and René Westerholt participated in a summer school of the DFG priority programme on “VGI”. GIScience Heidelberg is involved in that programme by two projects, one of which is dealing with data quality issues and another one that investigates the assessment of spatial assotiations in social media data. The…

  • Workshop on “spatial urban analytics with user-generated geodata”

    We’ve recently finalised the programme of a workshop on “spatial urban analytics with user-generated geographic information”. The event is conjoined with the 2017 International Conference at the Royal Geographical Society in London and is co-chaired by René Westerholt (GIScience Heidelberg). We received methodological as well as empirical contributions, which reflects the breadth of the complex…

  • Talk at AAG Meeting in Boston

    On Friday, our member René Westerholt held a talk at the Annual Meeting of the American Association of Geographers (AAG) in Boston. The talk which is entitled “Topological and scale-related issues in Twitter analyses through superimposed forms of spatial heterogeneity” was part of a special session on geographic data science organised by Alex Singleton from…

  • Seminar on “Spatial urban analytics” at Harvard

    Our team member René Westerholt recently held a joint session with Dr Guibo Sun from Hong Kong University. The session on “spatial urban analytics” was part of the Geography colloquium at Harvard University. Both talks were dealing with methodological issues. Thereby, René emphasised on technical issues in the spatial analysis of social media data. Dr…

  • 3rd CFP: Journal Special Issue “VGI Analytics” in Geo-Spatial Information Science and AGILE workshop

    VGI-Analytics 2017 Volunteered Geographic Information (VGI) and social media data have become part of our everyday lives over the past few years. Whereas in the early beginnings of crowd-sourced data the collection occurred primarily to isolated, individual platforms, contribution patterns are now beginning to be more intertwined between different platforms, both at the application level…

  • Prize of “Runder Tisch GIS” for GIScience Master Thesis on Geospatial Analysis of the German Software Industry (Jan Kinne, Heidelberg)

    The Master Thesis of Jan Kinne on the subject: “The Geographic Dispersal of the German Software Industry – Geospatial Analysis and Location Pattern Modeling” won the price “Nachwuchsförderpreis Geoinformatik 2017” of the “Runde Tisch GIS e.V.” in the category ‘Master Thesis’ with a value of 1.500 Euro. In addition Jan did also win the audience…

  • Invitation: Colloquium Talk by Jun.-Prof. Sven Lautenbach on Trade-offs Between Land use and Ecosystem Services

    We cordially invite all interested to our forthcoming talk in the GIScience colloquium next Monday, December 12, about quantifying trade-offs between land use and ecosystem services. Jun.-Prof. Sven Lautenbach will provide an overview of methods to assess the different environmental goods and services produced by land systems. Policy makers are in want of such information to…

  • Social Media Data: Topological Outliers and Their Influence on Spatial Analysis

    Social media data is one of the recent and prominent sources of georefrenced social information. It allows in-situ insights into the everyday lifes of ordinary people. For all that, social media data also confronts us with considerable analytical challenges. One of these challenges is the mingling of different user habits, functions of geographic space and,…

  • Two new DFG projects on VGI, OSM Quality and Social Media Analysis

    recently we were happy to receive the notification that two new research projects will be funded by the Deutsche Forschungsgemeinschaft (DFG) the German main funding agency for fundamental research. Both projects belong to the DFG Priority Programme “Volunteered Geographic Information: Interpretation, Visualisation and Social Computing“ (SPP 1894). The two projects are: A:) IntrisicOSMquality: A framework…

  • Geospatial Analysis of Disasters – Measuring Welfare Impacts of Emergency Relief, Workshop Heidelberg University

    IWH Symposium: Geospatial Analysis of Disasters Measuring Welfare Impacts of Emergency Relief today & tomorrow: July 18-19, 2016 at Heidelberg University, Germany (by invitation only) Natural disasters and man-made catastrophes pose a serious threat to the stability and prosperity of countries and the well-being and lives of many individuals worldwide. Methodological advances and better availability…

  • Establishing the “Heidelberg Institute for Geoinformation Technology” at Heidelberg University – A new project funded by the Klaus Tschira Foundation (KTS)

    A major project funded by the Klaus Tschira Foundation (KTS) Heidelberg is starting this July. The KTS will support the establishment of the “Heidelberg Institute for Geoinformation Technology” ( HeiGIT for short) within the Institute of Geography at Heidelberg University. This new project aims at improving knowledge and technology transfer from fundamental research into practice…
